To all whd'm it concern:

Be it known that I, Ismou Krrsnn, citizen of the United- States, residing at- Philadelhia, in the county of Philadelphia and tate of Pennsylvania, have invented certain new and useful Im rovements in Phonography, of which the ollowing is a specification.

My invention relates to an improvement in phonography. Izts object is to produce -original records in a. simple and eflicient manner and it is also one of its objects to produce direct from said original records co ies of same.

is to produce the original record. I prefer that the lines of record should be marked on the support without actual contact of the stylus or writing means and as it is necessary tume to illustrate mechanical means adaptet to produce such lines of record, so that persons versed in the art may practice my invention, I have illustrated in the accompanying drawing a device with the aid of which records may be produced Without actual contact of the stylus with the material on which the lines of record are to be produced, it being obvious that the mechanical arrangement may differ without departing from the scope of my invention.

In practicing my invention, it is necessary to produce two identical records and I have, therefore, recourse to means whereby identical lines of record may be simultaneously produced on two independent plates or disks. In the drawing, Figure 1 is a cross section of a recording mechanism with my device attached thereto. Figs. 2, 3, 4 and 5 are er- .s ective views of plates having mar ed 4 t ereon-the lilies of record in their different stages. Fig. 6 is a vertical transverse sec- I tifonal view of an electrolytic apparatus empltiyed in practicing the invention.

11 Fig. 1, 1 is the mouth piece of the usual sound-box; 2 the diaphragm; 3 the stylus attached to thediaphra m. This stylus is here partiall supportel by the movable lever 4 attac ed to the bar 5 and held in position by the support 6.

So far the device ma the usual phonogra h stylus being rov1d with aflcutting point, I substitute t erefor means to move therewith a device whereby roper material may be de osited on the p ate or disk without home contact with sand plate or disk.

7 is a reservoir containing the liquid 15. 8 are the means to regulate the flow of the liquid from said reservoir and 16 are the means to rovide ressure to said liquid. To the out et ofthls reservoir is connected a flexible tube 9 and to this tube is connected the pipe 10 p'rovidedw-ith the two orifices 11 and 12. One of these orifices is of somewhatlarger dimension than the other, so that a broader line canbe traced or marked with, In

' is theplate or disk 14.

The .fluid or liquid should be non-conducting and it is even preferred to make the same etch-resisting for the pur ose as will hereinafter be described. The liquid should issue from the reservoir in a very thin stream, and as the orificeshave to vibrate in accordance with the vibrations of the stylus, due to the vibrations of the diaphragm, which vibration of the orifices is permitted by the flexible tube 9, it is obvious that the liquid or fluid will be deposited on the solid surface in a manner so as to reproduce these vibrations. In this connection it will be understood that a relative movement between the reservoir 7 and the disks 13 and 14 should occur, that the reservoir may conform to the feed of the sound-box, and to this end the reservoir 7 should be properly supported in relation to the sound-box so that proper movement of the reservoir across the disks 13 and 14 may be had.

To practice my invention, it is,-as stated above, necessary to produce two identical records and in Fi s. 2 and 3' I have illustrated these reco s in which the lates or disks are designated by the numera s 13 and 14 and the lines of record by the numerals 17 and 18 respectively. After the production of the two records, I subject one of these records to a rocess whereby the lines of record are 1e in inta lio that is, depressed, and I then sub ect the second of said records to a rocess whereb the lines of record are ro uced in relie that is, raised above t e surface.

In m experiments, I have found that to accomp ish this purpose in a simple and efficient manner, it is only necessary to make one of these records the anode and-the second of these records the cathodein an electrol tic apparatus with the necessary electrolyte.

n Fig. 6 I have disclosed such electrolytic trated in'connection with the cathode, and

the disk 14 in connection with theanode, and by reason of this it is apparent that the electrolytic action Wlll cause a metallic deposit upon the free surface of the disk 13, while the free surface of the disk 14 will be eaten inch of surface exposed sufficient for practical purposes.

Throu h this rocess, copper-is deposited on the sur ace of the cathode, raisi this surface and leaving the lines of reco in their original state, whereb these lines of record arefor all practicapurposes depressed or in inta lio, and' the copper of the free surface of t e anode is eaten away leaving again the lines of record in their original state, and through-the eating away of the other parts of the surface of the late,

' the lines of record are- -for all practice purposes-raised above-the remami surface and are therefore in relief. T d produce copies from suchrecords, it is only necessaryto use one of the recordsas a male and the second of the records asa female and com pressing the necessary material, such for in-- stance as celluloid, etc., between the. two disks. 1 ,J. To br' the lines of record 'entirelyin alinement, have 'rovided the means sons to 100 the same at' the place and these means are here shown-as 21 and 22; one of these means being raised .andthe other depressed. f 1 I am well aware that instead of producmg the records in relief from .a metallic plate, the same results can be obtained bl}; the process of etching, ,butas some. meta lend themselthanvte: tflrrlathtelggto the electro process ee' 'nocess, it'is-o ,VIOIIS that one or the other i ay be practiced in accordance with uirements.

In my expenmen, have found'that tohave'tiitreoor ing liuesof one'i record th new record, for the reason thotone of these ords is then used as a male and the other of these records is used as a female and the ma: terials from which thecopy is to be made, has to compressed between the two records.

Having now described my inventiom'what I claim as new and desire to secure by Lettors Patent is 1. In phonography, the method, which consists in caus1 through the sound waves, a diaphragm to v1 rate, causing throu h said vibrations a non-conducting materia to be deposited simultaneously on the surfaces of two separate conductors, in accordance with the vibrations of said diaphragm, and cansing then the free surface of one of said conductors to be depressed and the free surface of the second of said conductors to be raised.

2. In phono aphy, the method of producin male and emale dies from original recor s, which consists in first producing simultaneously two original records, and then raising the free. surface of one record and de ressing the free surface of the second recor through the action of the current in an electrolytic apparatus. 3. In

consists in first producing simultaneously identical recording lines on two independent conductors with a non-conducting material, and then makil said records the anode and cathode, respectively, of an electrol tic apparatus whereby-the free surface of one of said conductors is' raised and the free sur- 'face of the second of said conductors is de- 1 I a suitable material between said die electrici h said a aratus whereb the free surfa'c ia of one said i-ecords i raised and the free surf e said records is do In testimon in presence 0 of the second of two witn .ISIDOR Krrsnsf;
